Hi guys, a little background....24 year old male. Have always had thick hair. Starting last summer (age 23 1/2), I noticed a little thinning mainly from more hair on the bathroom floor than usual.

Anyways, I've included some pics - and have also started taking 10,000mcg of biotin starting about 2-3 weeks ago. I didn't realize it was in this area until my mom (who is anal about stuff like this) pointed it out to me.
